Astrophysicist Neil deGrasse Tyson has earned a reputation not
just as one of America's leading scientists, but also as a fan
and critic of science fiction. He critiqued the science
behind "Gravity" and
praised the accuracy of "Interstellar."

So it's not a surprise Chris Weitz, one of the
writers of the "Star Wars" spin-off "Star Wars: Rogue One,"
tweeted at Tyson to ask for some help with the astronomy of
the film.
